Adding Math.h library to a existing project

kartheekgajjala — Mon, 23 Sep 2019 19:40:57 GMT

I am trying to use lround function and it requires math.h to be included but I am not sure how to include it to an existing project that I have created. I have just created a new C/C++ project. I have attached what the library settings are for my project below.

Hello Kartheek Gajjala,

Is there some error when you config like yours? Please take a screenshot show it.

Also what about the name of lib ?

There is a DOC about how to add static lib in MCUXpresso IDE:

How to create and use static library in MCUXpresso IDE

If still have problem, please attach your project and lib.

Have a great day,
TIC

I was using Redlib and I tried all 3 configuratoins of none, nohost and semihost. However when I try it with newlib it doesnt give me the error. Not sure why thats the case.

Redlib is a small C90 library implementation. See https://community.nxp.com/thread/389152
